Justin Timberlake is a 'softie'

Justin Timberlake gets emotional looking out at his fans on stage.

The 35-year-old singer is a "softie" and can't help but being overwhelmed by the "energy" and the fact people have chosen to see him as a way to escape and "check out from life", while also wanting to engage and connect with his performance.

He said: "I'm a softie. It happens some nights because you're only one man standing up there, and you're getting all of this. I feel like I look out in the crowd and see all these different walks of life, ages, sexes, races, and it makes me wonder, 'What are they going through? What is their life like?'

"We think we go to concerts so we can check out from life, but the truth is we want to relate; we want to connect. You say, 'Oh, I need a night out,'' and you think you're going away from your life.

"But you show up there and sing these lyrics, and even though they remind you of your life, you're thinking somewhere in the back of your mind, 'Five years from now, I'm gonna remember this moment.'

"There's all that energy: the synchronized clapping, the lyrics you wrote in a box of a room being sung back to you with such joy -- it's a lot to take in."

Justin's upcoming concert film, 'Justin Timberlake + The Tennessee Kids' features the final stop of his '20/20 Experience World Tour' in Las Vegas and he is glad they chose the last shows because he had been through so much with his band by that point.

He told Billboard: "When you spend two years with people, there's good and bad scar tissue, right? More texture, more wrinkles and more heart because of all that shared experience. I'm glad we did it this way."
